Daim ntawv thov ntawm Kev Kho Tus Kheej Txheej Tshuab hauv Hmoov Txheej

Txij li xyoo 2017, ntau tus neeg muab tshuaj tshiab nkag mus rau hauv kev lag luam hmoov txheej tau muab kev pabcuam tshiab rau kev nce qib ntawm cov hmoov txheej tshuab. Cov txheej txheem kho tus kheej los ntawm Autonomic Materials Inc. (AMI) muab kev daws teeb meem rau kev txhim kho corrosion ntawm epoxy. hmoov txheej.
Cov txheej txheem kho tus kheej yog ua raws li microcapsule nrog cov txheej txheem-plhaub uas tsim los ntawm AMI thiab tuaj yeem kho tau thaum txheej txheej puas lawm. Qhov no microcapsule yog tom qab sib xyaw hauv kev npaj cov txheej txheem hmoov txheej.

Thaum kho epoxy hmoov txheej puas lawm, cov microcapsules yuav tawg thiab ntim rau hauv kev puas tsuaj. Los ntawm qhov kev xav ntawm cov txheej txheem txheej, qhov kev kho tus kheej no yuav ua rau lub substrate tsis raug rau ib puag ncig, thiab nws zoo heev pab tiv thaiv corrosion.

Dr. Gerald O. Wilson, Tus Lwm Thawj Coj ntawm AMI Technologies, tau nthuav tawm qhov kev sib piv ntawm cov txiaj ntsig ntawm kev ntsuas ntsev ntsev ntawm cov hmoov coatings nrog thiab tsis ntxiv microcapsules. Cov txiaj ntsig tau pom tias cov epoxy hmoov txheej uas muaj cov microcapsules tuaj yeem kho cov khawb thiab txhim kho cov tshuaj tsw qab. Cov kev sim qhia tau hais tias cov txheej txheej nrog microcapsules tuaj yeem ua rau muaj kev tiv thaiv corrosion ntau dua 4 zaug nyob rau hauv tib cov tshuaj ntsev ntsev.
Dr. Wilson kuj tau txiav txim siab tias thaum lub sijhawm tsim khoom tiag tiag thiab txheej txheej ntawm cov hmoov txheej, cov microcapsules yuav tsum tswj lawv txoj kev ncaj ncees, txhawm rau kom ntseeg tau tias cov txheej txheem tuaj yeem kho tau zoo tom qab cov txheej txheem tawg. Ua ntej, txhawm rau zam kev puas tsuaj ntawm cov qauv microcapsule los ntawm txheej txheem extrusion, tom qab sib tov raug xaiv; Tsis tas li ntawd, txhawm rau kom ntseeg tau tias muaj kev sib cais ua ke, cov khoom siv plhaub uas tau sib xws nrog cov khoom siv txheej hmoov ntau yam; Thaum kawg, lub plhaub kuj suav tias yog qhov kub siab ruaj khov, Tsis txhob tawg thaum cua sov.
Qhov tseem ceeb ntawm cov thev naus laus zis tshiab no yog tias nws muab kev txhim kho zoo heev hauv kev tiv thaiv corrosion yam tsis tas siv cov hlau, hexavalent chromium, lossis lwm yam kev puas tsuaj. Cov txheej txheem no tsis tsuas yog muaj cov khoom siv tau zoo, tab sis kuj muab cov khoom thaiv zoo heev txawm tias tom qab kev puas tsuaj loj rau substrate.
